Just 2 cents worth, rotating the picture to portriat 90 degrees clockwise might protray the alphabet 1 and also makes it interesting...dont know how good it will be though.
context - during the old film days
the resulting image on the negative/slides is the same size as the subject
for example: if you take a photo of a ruler's scale and then measure the resulting image on the film, 1cm scale on the ruler would be 1cm in lenght on the film.
